With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting, because LEDs are far superior to traditional lighting products in terms of light-emitting principles, energy saving, and environmental protection. LED lights can generally be divided into patches and lamp beads. What are the connections and differences between them? Let’s follow the editor to see whether LED light patches or lamp beads are better.
1. Introduction to LED SMD lights
LED SMD lights are made of FPC circuit boards, LED lights, and high-quality silicone sleeves. Waterproof, low-voltage DC power supply is safe and convenient, and the luminous colors are diverse and bright. When used outdoors, it can resist UV aging, yellowing, and high temperature. This product is widely used in building outline lights, entertainment venues, quasi-decorative lighting, and advertising decorations. Lighting lighting field. }
Product features:
1. It can be bent at will and fixed on concave and convex surfaces at will.
2. Every 2 LED lights can form a circuit.
3. Small size and rich colors.
4. It has high brightness and adjustable lighting angle. The installation and length can be customized according to requirements.
5. Energy saving: constant current drive, ultra-low power consumption, electro-optical power close to 100%.
6. Environmentally friendly: no ultraviolet or infrared radiation, no heat, and no risk of mercury leakage.
7. Longevity: 50,000-80,000 hours, more than 10 times the life of traditional fluorescent lamps.
2. Introduction to LED lamp beads
LED is (lightemittingdiode) in English, and LED lamp bead is the English abbreviation of light-emitting diode, abbreviated as LED, which is a popular name.
1. Voltage: LED lamp beads use low-voltage power supply, and the power supply voltage is between 2-4V, which varies according to different products, so it is driven by a safer power supply than high-voltage power supply, which is particularly suitable for In public places;
2. Current: The working current is 0-15mA, and the brightness becomes brighter as the current increases
3. Efficiency: The energy consumption is higher than that of the same light Effective incandescent lamps are reduced by 80%.
4. Applicability: It is very small. Each unit LED chip is 3-5mm square, so it can be prepared into devices of various shapes and is suitable for volatile environments.
5. Response time: The response time of incandescent lamps is milliseconds, and the response time of LED lamps is nanoseconds.
6. Environmental pollution: no harmful metal mercury.
7. Color: Changing the current can change color. Light-emitting diodes can easily adjust the energy band structure and band gap of the material through chemical modification methods to achieve multi-color light emission of red, yellow, green, blue and orange. For example, an LED that is red when the current is small can turn into orange, yellow, and finally green as the current increases.
3. Which LED lamp is better, SMD or lamp beads?
1. The power of LED lamp beads is different
High-power LED lamps generally use 1W high-power LEDs Lamp beads, 1-3W high-power LED lamp beads, COB high-power. High-power lamp beads A single LED can have a maximum power of more than 200W.
Low-power LED lamps generally use SMD lamp beads, which mainly include these types: 5050 lamp beads, 0.2W each, 3528 lamp beads, 0.06W each, 3014 lamp beads, each 0.1W, 5630 lamp beads, 0.5W each, 5730 lamp beads, 0.5W each.
2. Different costs
From the perspective of product cost, the cost of high-power LED lamp beads is higher than the cost of low-power LED lamp beads. First, the cost of high-power LED itself is higher; Second, high-power LEDs require aluminum heat sinks, while low-power LEDs can meet the requirements by using ordinary circuit boards and natural heat dissipation.
3. Different LED lamps are used
High-power LEDs are basically used in products that require high light sources per unit area, such as LED ceiling lights and LED floodlights. , LED bulbs, street lights, etc.
Low-power LEDs are basically used in products that have less patching area, are difficult to dissipate heat, and do not have high requirements for light source emission per unit area, such as LED ceiling lamps, LED fluorescent lamps, LED panel lights, LED light strips, etc.
Generally speaking, SMDs are good. After all, in addition to good heat dissipation and a large light-emitting angle, reasonable design will make your bulb have no dark areas. In contrast, lamp beads have no advantages. .
